` (ci. isi- 97) 2 Claims.

This invention relates to improvements in check-controlled apparatus andhas `as its principal object the provision of means for preventingfradulent or accidental jamming of coins in a coin testing apparatus ofthe type including a reciprocable coin slide -and a coin feeding chutecoacting therewith for feeding coins away from the testing apparatusafter acceptance, the invention relating especially to the provision ofmeans on said slide which will be normally in blocking position relativeto the feeding chute and which will be effective to prevent theretrograde or return movement of previously fed coins into the cointesting device.

Viewed from another aspect, it is an object of the invention to providea coin testing device having some form of reciprocable mechanism foreffecting transport of a coin from a depositing position to a dischargeposition,` and a laterally projecting feeding chute for accepted coinsand mounted to receive accepted coins at said discharge position andmove the coins in step by step progression along the chute for depositin a receptacle, said slide mechanism, in-

3 cluding a slide member having an offset edge portion, constituting ablocking member which isV normally disposed in blocking position acrossthe mouth of the feeding chute, whereby deliberate or accidentalmovement of the coins back into the coin testing device Will beeffectively prevented.

Other objects, advantages, and economies residing in the inventionrelate to the form, location, and operation of certain structuralfeatures thereof, all of which will become apparent as the followingdescription proceeds in view of the annexed` drawing, in which:

Fig. 1 is a top plan view of a combination check testing unit andfeeding chute;

Fig. 2 is a fragmentary vertical longitudinal section along line 2 2 ofFig. 1;

Fig. 3 is a fragmentary lateral section, viewed along line 3 3 of Fig.1;

Fig. 4 is a fragmentary perspective of the feeding mechanism for thefeed chute;

Fig. 5 is another fragmentary perspective similar to Fig. 4, but showingthe feeding mechanism in feeding position; and

Fig. 6 is a perspective view of the coin transporting slide providedwith the novel blocking means.

This application includes matter divided from U. S. application SerialNo. 146,836, as well as matter not disclosed in said application.

In a preferred embodiment of the invention,

opening 2l above the slide.

i3, mounted in the sleeve portion of the frame,

for access exteriorly of the cabinet.

The slide i3 is provided with a lcoin receiving pocket lll in which asuitable coin is placedfor transport by subsequent movement of the slide*I0 inwardly of the cabinet (to the right, Fig. 1) so as to move thecoin past certain testing means including, for example, the dogs l5 andI6 and the magnet l'l, the testing means being of any Y suitable form,suchfor example as that described l5 in detail in thev aforesaidcopending application. Referring to Fig. 2, the yframe structure for thetesting apparatus is arranged to provide a shelf or ledge i8 at a levelbelow that of the slide i3 and rearwardly of the testing means, so that2.20 the transported coin, after passing the testing means, may droponto the ledge i8 for subsequent movement by a depending lug I9 (Fig. 1)in the slide i3., into a well 2li lying beneath a sight A spring pressernger 22 serves to guide the coin downwardly toward a coin pocket 23 inan auxiliary coin slide 24 (the form of which is shown in Fig. 6) forsubsequent deposit on the floor 25 of an auxiliary coin feeding chute 26v31) (Fig. 5).

IThe coin feeding chute 26 is preferably of the type described in theaforesaid copending application and is constructed so that the oorsection 25 thereof extends parallel with the frame35 structure ii)beneath the auxiliary slide 24, being attached to the bottom of theframe by means such as the screws 2l, there being a'laterally projectingchute section 28 (Figs. 1 and 5) having a mouth 29 positionedsubstantially opposite 40 the bottom of the Well 2B so that acceptedcoin elements passing through the pocket 23 in the auxiliary slide 24onto the floor 25 may be moved laterally into the feeding chute.

I'he foregoing lateral movement of accepted 45 coins is preferablyaccomplished by a feeding cam 3@ pivotally mounted as at 3| on the underside of the auxiliary slide 24 for oscillatory movement toward and awayfrom the mouth 29 of the feeding chute, the cam being so designed 50 ythat when it is in the position illustrated in Fig. 4, the nose portion32 thereof will be at the far side of a coin element indicated in dottedlines at 33. The feeding cam 3U is provided with an irregular cam slot34 shaped and situated to 55 CFI receive a stationary camming pin 35mounted on the floor 25 in such manner that as the auxiliary slide 24 isreciprocated, the cam member 3E! Will be oscillated as a result of themovement of the slot portion 34 relative to the pin 35, so that coinelements 33 will be swept into the mouth 29 of the feeding chute.

The auxiliary slide is reciprocated through the agency of an upstandingpin 36 mounted thereon so as to project into a longitudinal slot 31(Figs. 1 and 3) in the main slide E3, there being a shoulder 38 on slidei3 and projecting into the slot 31 so that after the main slide i3 hasbeen moved inwardly (toward the right, Fig. 1) a certain amount lessthan its entire displacement,

the shoulder 38 will bear against the pin 325 andmove the auxiliaryslide the remainder of the distance With the main slide, and since thefeeding cam 30 is pivoted as at 3i to the auxiliary slide, the cam Willbe moved in a direction to push a coin 33 into the feeding chute.

It is possible to cause deliberate or accidental jamming of the entireapparatus by rattling, jarring, or striking the apparatus, andparticularly the auxiliary feed chute 2B, in a manner which will effecta rearward or retrograde movement of coins in the feed chute backthrough the mouth 29 and into the bottom region of the Well 20, thefeeding cam 3S normally being Withdrawn as in Fig. 4 When the slide i3is in a normal coin receiving position of Fig. l.

In order to prevent such accidental or deliberate jamming of themechanism, the invention provides means for automatically blocking themouth of the auxiliary feeding chute at all times except when coinelements are actually being vmoved into the mouth of the feeding chute.A

preferred arrangement of this blocking means is shown particularly inFig. 6 wherein the auxiliary coin slide 2li has an offset or dependinglongitudinal flange Il@ arranged on the longitudinal edge portionthereof nearest the feeding chute section 28, the flange lli) being soarranged and constructed (Figs. 3 and 5) that when the main slide I3 isin its normal coin receiving position, and the auxiliary slide 24 isalso in normal position with its pocket 23 in register with the Well 2G,the iiange portion lll Will be disposed in coin blocking position acrossthe mouth 29 leading to the feeding chute 28, so that retrogrademovement of coin elements from the latter is positively preventedregardless of the cause.

The feeding chute 28 may be of any desired construction and may includeadditional testing means, such for example as the undersized-diameterdrop-out opening indicated in dotted lines in Fig. l, and thecooperating spring presser 46 Which is effective to support coinelements of proper diameter in their step by step movement past theopening 45 and toward the discharge end 41 of the feeding chute. Adetailed description of a suitable feeding chute of this type is setforth in the aforementioned copending application.

In its broader aspects, the invention relates particularly to theprovision of the automatic blocking means actuated by the auxiliaryslide 24 for blocking movement of coin elements into a feeding chute,Whether that chute includes additional testing mechanism or not; and itmay be pointed out that the blocking means may be applied to the mainslide I3 as Well as to any auxiliary slide mechanism. All equivalentchanges in form, location, and operation of the means of the inventionare intentionally included Within the call of the appended claims.
